I remember that when I was college student I ever wanted to make a nice project and my teacher of Digital Electronic passed a lesson for the semester that was the development of a Digital Clock without microncotroller. So this project just would use IC with C-MOS technology.

I will teach you how to do a simple digital Clock. Are you Ready?

This project helped a lot with a Digital Eletronica material and now I can do different projects thanks to this one.

Step 2: GET STARTED WITH PROJECT

I advise to first build the 7 display segments, testing the same, but if you has difficulty with this, I have a video helping "HOW TO TEST 7 SEGMENT DISPLAY".

Be Careful with the encoder (4029) and decoder (4511). They are extremely importants for the correct functionament of the circuit.

Step 3: MORE ABOUT THE PROJECT

If you are here probably it is because you got the project. So I will say more about him. The 555 is responsible for do the clock. He has 2 states, 0 and 1, when him are in level 1 increment a bit for the encoder that put more one bit for the encoder do a logic that the display show the number in the display. The logic gates are responsible for do the logic of the seconds and minutes that increment hours. I'm sorry for English mistakes, I'm learning and I do not want to use translator.
